LTC1755 - Smart Card Interface
LTC1755 - Smart Card Interface - Linear Technology（凌力尔特）
An internal charge pump DC/DC converter delivers regulated 3V or 5V to the Smart Card, while on-chip level shifters allow connection to a low voltage controller. All Smart Card contacts are rated for 10kV ESD, eliminating the need for external ESD protection devices.
Input voltage may range from 2.7V to 6.0V, allowing direct connection to a battery. Internal soft-start mitigates start-up problems that may result when the input power is provided by another regulator. Multiple devices may be paralleled and connected to a single controller for multicard applications.
Battery life is maximized by 60μA operating current and 1μA shutdown current. The narrow SSOP packages minimize PCB area for compact portable systems.
